Abstract

Increased viscosities are particularly required in cosmetic surfactant formulations. The thickeners hitherto used have some considerable disadvantages concerning their ecological profile. For this reason, novel thickener systems based on alkyl polyglycosides, polymers and, where appropriate, foreign electrolytes, which do not have these disadvantages, are proposed. These thickener mixtures are mainly used in cosmetics with conventional basic surfactant formulations.

Es bestand daher die Aufgabe, ein System zur Viskositätserhöhung wäßriger, kosmetischer Tensidzubereitungen, das die oben erwähnten Nachteile nicht aufweist und zu einer toxikologisch, ökologisch sowie ökonomisch befriedigenden Lösung führt, aufzufinden. It was therefore the object of aqueous, a system for increasing the viscosity, cosmetic surfactant formulation, which does not have the drawbacks mentioned above and results in a toxicologically and ecologically as well as economically satisfactory solution to be found.

Die erfindungsgemäß eingesetzten Alkylpolyglycoside können nach bekannten Verfahren auf Basis nachwachsender Rohstoffe hergestellt werden. The alkyl polyglycosides used in the invention can be prepared based on renewable raw materials by known methods.Beispielsweise wird Dextrose in Gegenwart eines sauren Katalysators mit n-Butanol zu Butylpolyglycosidgemischen umgesetzt, welche mit langkettigen Alkoholen ebenfalls in Gegenwart eines sauren Katalysators zu den gewünschten Alkylpolyglycosidgemischen umglycosidiert werden. For example, dextrose is reacted in the presence of an acidic catalyst with n-butanol to form butyl polyglycoside which are also umglycosidiert with long-chain alcohols in the presence of an acid catalyst to form the desired Alkylpolyglycosidgemischen.
